Phonon Invisibility Driven by Robust Magneto-Elastic Coupling in AlFeO3 Thin Film

Date 13 Jan 2019
AbstractThe thin films of lead free magneto-electric compound AlFeO3 have been deposited using pulsed laser deposition technique. X-ray diffraction, X-ray absorption spectroscopy and reflectivity measurements established the orthorhombic structure and material density of 4.5g/cc which is comparable with bulk AlFeO3. The Raman mode corresponding to AlFeO3 was found to vanish when magnetic field of 800 Oe was applied at room temperature. Additionally, it was observed that the Raman phonon mode present at the room temperature becomes invisible in the temperature window of 280K-236K and reappears below it. The detailed analysis of magnetization showed a change in magnetic order in this temperature interval. The invisibility of Raman phonon mode corresponding to AlFeO3 have been attributed to the lattice deformation caused by the magnetoelastic effect. The presence of strong spin-lattice coupling is also validated by the renormalization of phonon frequencies below 200 K.
